Personally I like a date complication, and preferably a day as well. As well as the convenience of having the extra information to hand I find it makes a watch more interesting to look at, especially blue Saturdays and red Sundays. To me date-free watches just look incomplete.
But I know a lot of people dislike them and Iím interested to know why. And if one of the options in the poll coincides with your reason please vote.
